sorry to bump this four month old thread but it is extremely relevant and it makes the most sense to post here.
i'm having the same problem: my girlfriend bought a 20.1" SCEPTRE widescreen LCD monitor that said HDCP in parantheses (but nowhere else) to use for herself and the PS3. the monitor is 1080i/1080p HD mode ready but apparently it is actually NOT hdcp complaint (how does that even make sense...)
according to the US playstation 3 general forums, i am not getting a signal with HDMI>DVI because the monitor is not HDCP, but this seems like bs because i heard that any monitor should display non hdcp media (like the ps3's cross media bar), in other words, get a video signal.
one problem i think might be that i don't know how to configure the monitor to accept HDMI. all i was doing was hitting the signal change button. i can't find anything about hdmi or dvi in the menu. i tried changing the PS3 to hdmi but that didn't get a signal...
also according to the US Playstation 3 general forums, i could use a component>DVI connector or something, but the only female component to male DVI that i could find requires certain graphics cards with up to date drivers. doesn't sound right?
i tried connecting the PS3 to two different non HD lcd monitors and this HD ready monitor with two different HDMI>DVI connecters and never got a signal! so it must be not setting the monitor up right, not setting the ps3 up right, or hdmi-dvi just doesn't work? help! i swear sony used black magic when they made these dumb DRMs and HDCP!
